DirectFB is built with --disable-mmx on ix86. I believe --disable-mmx should be removed because this is just something that controls whether MMX support is compiled in -- whether to actually use MMX is detected by DirectFB at runtime. Not sure about --disable-sse, it "smells" the same as --disable-mmx but I couldn't find anything that would be actually affected by --disable-sse on a quick look at the sources.
Thx for the report Ville. Actually I lack time to double check this for the current release. I just remember some options like that was needed for PPC previously. Now it would be best to test for the coming next release unless you want to have it in current releases. So it would be best for you to request the ACL for directfb actually, as I don't want to be a locker in this case.
Being a provenpackager, I don't think I need an ACL in order to be able to push and build it. If you want, I can push a build that removes --disable-mmx and --disable-sse for Rawhide, but please be aware that I don't have a single ix86 box to test this with (x86_64 only here, I just noticed the build flags while looking for something else).

Looking at that again, and I think the disablement was intended. We cannot suppose mmx or sse on i686 whereas sse2 is a default on x86_64 ?
Please see the initial comment...
OK, I've finally got it. Actually I haven't seen any occurrence of USE_SSE in the code.
